## Why Your ISP's Rented Modem is Costing You Money
Comcast charges $15/month for a rented modem. Over 3 years, that's $540 — enough to buy a premium modem and a top-tier Wi-Fi 7 router. Here's what I actually recommend to homeowners in Nashville after seeing thousands of setups.
## Top Picks for 2026
### Best Modem: Arris SURFboard S33 (DOCSIS 3.1)
~$130 on Amazon. This is a pure modem — handles Comcast's OFDM channels properly and supports multi-gig speeds. Pair it with your own router for best results.
### Best Wi-Fi Router: Eero Pro 7
~$200 on Amazon. The Eero Pro 7 is what I personally set up in homes when clients want zero-headache Wi-Fi. The app is excellent, the range is real-world tested, and it supports Thread for smart home devices.
### Best Budget Option: TP-Link Archer BE3600
~$130 on Amazon. Wi-Fi 7 on a budget. Great for homes under 2,000 sq ft with a clear line of sight to the router.
## What I Tell Every Homeowner in Nashville
Before buying new hardware, check your coax signal level. A corroded F-connector on the outside of your house can drop your downstream power by 6+ dB, which will destroy your speeds regardless of what equipment you buy inside. I've seen it dozens of times.
If your modem's signal level shows downstream power below -7 dBmV or above +7 dBmV, call your ISP to fix the line — not hardware.
